Custom Magnetic Screen Door: Get the Perfect Fit for Any Door

Most magnetic screen doors come in a handful of standard sizes. Most door openings don't match those sizes exactly. That gap — literally — is why so many people buy a screen, install it, and still find insects getting in around the edges. A custom magnetic screen door solves this at the source.

What Is a Custom Magnetic Screen Door?

A custom magnetic screen door is made to your specific door measurements rather than a preset size. You measure the width and height of your door opening, submit those dimensions, and receive a screen cut precisely to fit — no overhang, no gaps, no trimming required.

The result is a screen that sits flush against the frame on all four sides. Standard screens leave gaps at the edges because they're designed to fit a range of openings rather than one specific size. Custom screens don't have this problem.

Who Actually Needs a Custom Magnetic Screen?

Non-standard door sizes. Older homes, bespoke builds, and many European-style properties have door openings that don't match standard US dimensions. If your door is wider than 40", taller than 82", or an unusual combination of both, standard screens won't cover the opening properly.

Sliding glass doors. A standard sliding door opening is 72" wide or more — too wide for a single standard magnetic screen. Custom screens can be made to cover the full width in one panel.

French doors. Double doors open to a wide central space. A custom screen sized to the full opening (rather than two narrower panels) gives a cleaner result.

Anyone who has already returned standard screens. If you've bought two or three screens and they all had edge gaps or didn't quite reach the frame, the problem isn't the brand — it's the sizing. Custom is the fix.

RVs and campers. RV door openings are notoriously inconsistent in size. Custom-fit screens are one of the most practical solutions for RV owners who want insect protection without modifying the door.

How CoverWith's Custom Process Works

CoverWith is the dedicated custom magnetic screen door option for the US, UK, and Australian markets. The process is straightforward:

1. Measure your door opening. Width and height in inches (or cm for UK/AU customers). Measure the opening itself — the space between the inner edges of the frame — not the door panel.
2. Submit your dimensions. Enter them when placing your order on coverwith.com.
3. Receive your screen. Made to your measurements, shipped to your door.
4. Install in 15 minutes. The same hook-and-loop tape installation as any magnetic screen — just fitted exactly.

CoverWith uses fiberglass mesh (more durable than the polyester used in most budget screens) and industrial-grade hook-and-loop tape that bonds firmly to most frame materials.

Custom vs Standard: When Standard Is Fine

Custom isn't necessary for everyone. If your door opening is a standard size — roughly 32"–36" wide and 80" tall — an off-the-shelf screen from Magzo, Homearda, or Flux Phenom will fit adequately. These cost $15–30 and are widely available.

The trade-off is small but real: standard screens are designed to fit a range of openings, so they're slightly wider or taller than any specific door. This creates small gaps at the edges that let in some insects. For a secondary door in a low-bug environment, that's acceptable. For a main door in a mosquito-heavy area, it isn't.

Custom screens cost more than standard options but significantly less than retractable or framed screen door installations. For a door that gets daily use, the improved seal is usually worth it.

Measuring Your Door for a Custom Screen

Getting the measurement right is the most important step. Here's how:

Width: Measure the distance between the inner faces of the left and right door frame, at the widest point. Measure at three heights (top, middle, bottom) and use the smallest measurement if they differ.

Height: Measure from the top of the opening to the floor (or threshold). Measure at three widths and use the smallest.

Note any irregularities. If your frame has a significant bow or if the opening is clearly not a rectangle, note that when ordering — most custom screen makers can accommodate minor variations.

FAQ

Can you get a magnetic screen door in custom sizes? Yes. CoverWith specialises in custom-sized magnetic screen doors. You submit your exact dimensions and the screen is made to fit your specific opening.

How much does a custom magnetic screen door cost? CoverWith's pricing varies by size. Custom screens cost more than standard off-the-shelf options but less than retractable or framed installations. Check coverwith.com for current pricing.

Is a custom screen door worth the extra cost? For non-standard openings, yes — because standard screens won't fit properly regardless of price. For standard openings, it depends on how much edge-gap performance matters to you.

How do I measure for a custom magnetic screen door? Measure the width and height of the door opening (inside frame edge to inside frame edge). Take three measurements across width and height and use the smallest value for each.

Can custom magnetic screens be used on French doors? Yes. CoverWith can make a single panel to cover the full width of a French door opening, or two coordinated panels depending on the design.

Final Thoughts

A custom magnetic screen door is the right choice for anyone with a non-standard opening — and a significant upgrade for anyone who's been frustrated by off-the-shelf screens that almost fit. The process is simple: measure accurately, submit your dimensions, install in 15 minutes. The result is a screen that actually seals your doorway rather than approximating it.

For standard door sizes, a good off-the-shelf screen does the job. For everything else, CoverWith's custom option is the practical solution.
